Method for detecting curve points in input image, involves determining curve points in input image by selecting pixels of image whose associated curve intensity coefficient satisfies predetermined selection criteria

摘要

The method involves obtaining cross intensity coefficient from difference between gradient angles, and balancing associated coefficient for pixel of an input image. Curve intensity coefficient is obtained consequently. The curve points in the input image are determined by a determining unit by selecting pixels of the image whose associated curve intensity coefficient satisfies predetermined selection criteria. Independent claims are also included for the following: (1) a device for detecting curve points in an input image (2) a computer program comprising instructions to perform a method for detecting curve points in an input image.
